Have at present fuel oil drive and battery power two big class, its intermediate fuel oil drive fork truck refer to using bavin Water Oil Or Gas be
Fuel, is provided the fork truck of power by electromotor.Electromotor produces heat in work process, such as not in time to coolant therein,
Transmission oil and in cold air inlet etc. radiated, then can affect its performance.At present, mainly using cooling fan, electromotor is carried out cold
But, and cooling fan is to be driven through gear or belt pulley by engine crankshaft so that the rotating speed of cooling fan with start
The rotating speed of machine is proportional.As long as electromotor is in work, fan is operated by constant-speed ratio, is actually needed with electromotor
Optimum working temperature no direct relation.
Utility model content
In order to solve the above problems, this utility model provides a kind of forklift engine electric control cooling system.
A kind of forklift engine electric control cooling system, including engine control module with to engine charge, coolant, biography
The cooling fan that dynamic oil is radiated, is respectively equipped with described engine charge, coolant, transmission oil and detects the first of its temperature
Temperature sensor, second temperature sensor, three-temperature sensor, described first temperature sensor, second temperature sensor,
The outfan of three-temperature sensor is all connected with engine control module；Described cooling fan is provided with for detecting its rotating speed
Speed probe, the outfan of described speed probe is connected with engine control module；The motor of described cooling fan
It is connected driving with electric-controlled silicon oil clutch, the input of described electric-controlled silicon oil clutch is connected with engine control module.
Scheme further, described cooling fan is connected with radiator.
Further scheme, the material of described radiator is aluminum, in order to engine coolant, in cold air inlet, change speed gear box
Transmission oil or truck hydraulic oil etc. are partly or entirely carried out concentrating radiating.
Automotive engine control module (ecm) be electromotor control core component, be forklift engine carry existing
Part, it, according to the input information of each sensor, controls fuel oil injection and the time of ignition of electromotor, and is other output devices
Optimal control instruction is provided.This utility model is not related to its internal structure, operation principle and its procedural problem, only relate to its with
Annexation between miscellaneous part.
This utility model adopts electric-controlled silicon oil clutch as the rotational power transfer device of cooling fan, realizes cooling wind
Dynamically associating between fan rotating speed and radiating requirements；And engine charge, coolant and transmission oil are gathered by temperature sensor
Temperature and cooling fan rotary speed data, by the function of engine control module itself, realize engine control module and
The transmission of multiparty control signal between electric-controlled silicon oil clutch, make electric-controlled silicon oil clutch realize to engine charge, coolant,
Transmission oil and hydraulic oil carry out multiparty control, improve control accuracy, realize infinitely variable speeds.
Its concrete operating principle is as follows:
The rotating speed of the temperature of engine charge, coolant and transmission oil and cooling fan is acquired respectively by sensor
And pass to engine control module, when raising or declining occur in each point temperature, engine control module is according to cooling fan
Speed probe is simultaneously improved by control electric-controlled silicon oil clutch or reduces the rotating speed of cooling fan, with reaching, electromotor is entered
The temperature of gas, coolant, transmission oil etc. carries out accuracy controlling.
So this utility model in time, is accurately controlled it is ensured that each part is in optimal work shape by each point temperature
State, reduces fault rate, improves reliability, increases the service life, and improves overall performance；In addition, the rotating speed of cooling fan and each point
Temperature becomes to quantify to correspond to, and reduces its consumption to engine power, reduces fuel consumption, improves the feature of environmental protection and the energy-conservation of vehicle
Property,, with respect to definite proportion driven type, under most of operating mode, rotating speed is relatively low for it, reduces noise pollution to a certain extent, improves
Human engineering comfortableness.
